HDS03.1-W100N-HS78-00-FW Bosch Rexroth Indramat

Product Description:

The HDS03.1-W100N-HS78-00-FW is a modular drive controller manufactured by Bosch Rexroth Indramat for the HDS Drive Controllers series. Installed inside an industrial cabinet, it operates as the power stage between a motion-control CPU and the servo motors that position tooling or material. By rectifying shared DC-bus energy, modulating three-phase currents, and supervising feedback channels, the unit supplies the torque accuracy demanded by packaging machinery, handling robots, and machining centres while allowing regenerative energy to circulate to neighbouring axes.

Motion commands reach the unit through the fibre-optic SERCOS interface, providing deterministic setpoint and diagnostic traffic across the axis group. Internally, heat is expelled by a built-in internal air blower, so external ducting is unnecessary. The power stage supports a continuous output of 100 A, giving ample headroom for rapid acceleration on high-inertia loads. Parameter structure, fault codes, and firmware layout follow the DIAX04 control family, enabling technicians to apply a unified service toolset. Hardware identification tag 03 distinguishes this line variant and determines connector arrangement, fuse sizing, and blower-speed thresholds.

Within the product tree, version 1 is the initial hardware release and is listed with no alternate versions, simplifying inventory planning for maintenance crews. The controller originates from Bosch Rexroth Indramat, and its mechanical envelope aligns with the rest of the HDS Drive Controllers rack, so retrofits can reuse existing busbars and wiring guides. Because airflow is self-contained, cabinet planners only need to reserve clearance for exhaust vents, and the fibre-optic command link avoids ground-loop noise; together these traits simplify enclosure design without compromising dynamic performance.
